TSMC taps GlobalFoundries to bolster US silicon interposer production in $2B deal

TSMC’s $2 billion multi-year deal with GlobalFoundries is a strategic move to expand U.S.-based advanced packaging capacity for AI-era semiconductors, especially silicon interposers used in high-bandwidth memory and multi-die chips. For CIOs and technology leaders, the key takeaway is that domestic supply-chain resilience for AI infrastructure is improving, but the packaging bottleneck will remain a constraint through at least 2028, so procurement, platform roadmaps, and deployment timing still need to account for limited near-term supply.
